Abstract
Wave properties such as interference are demonstrated with a tabletop wave tank, displayed using an overhead projector.
Principles Illustrated
Wave properties are universal to all waves. Observing diffraction and interference in water waves can help students understand these phenomena in light and sound waves.
NCEA & Science Curriculum
SCI 1.3, PHYS 1.4, PHYS 2.3, PHYS 3.3
Instructions
Careful lighting is the key. Video does not work very well, it is better to see this demo live. We have various accessories.
Safety
Individual teachers are responsible for safety in their own classes. Even familiar demonstrations should be practised and safety-checked by individual teachers before they are used in a classroom.
